We should get to buf_ring.h soon. However, we also need to pause and update the atomic(9) man page. It defines the semantics of acquire and release in a way that is inconsistent with the architectures that natively support the release consistency model, e.g., arm64 and ia64, as well as the C11 and C++11 standards. Lines 330 through 339 of the patch in D1945 is one example of where the incorrect definition in the current man page has an effect.
